WHEEL.

Application led December 22, 1920.

['c all 'whom 'it may concern.'

Be it known that i, ALFRED MATHIS, a citizen ot the United States, residing at Eldorado, in the county ot Saline and State of illinois, have invented certain new and useful Improvements in a l/Vheel; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of the invention is to provide a wheel with a demountable rim having simple and efficient means whereby the rim is secured to the telly under conditions insuring a substantial locking of the parts when in use while affording facility in the removal and replacement of the same; and with these objects in view the invention consists in a construction and combination of parts ot which a preferred embodiment is shown in the drawings, wherein- Figure 1 is a side view of a wheel having a telly and rim construction embodying f the invention.

- cally opposite side of the wheel trom said in the rim 12 and telly 13 the rim and telly are provided with complemental interlocking elements 14 and 15 consisting in the construction illustrated of ribs disposed respectively longitudinally and transversely of said rim and telly and having tapered seats 16 and 17 which are adapted to be brought Serial No. 432,476.

into interlocking relation by a relatively transverse or radial movement ot the rim and telly, or by that movement of the rim relative to the telly which is necessary to cause the extension of the valve tube carried by the tire seated on the rim through the opening 11 of the telly.

At spaced points, remote from the valve openings and 11, the rim and telly are provided with other interlocking elements consisting ot the wedges 18 and the transverse tapered seats 19 adapted for engagement by a transverse relative movement ot the rim and telly as in swinging the rim toward the telly atter having efi'ected the seating of the valve tube in the opening 11, the seats 19 being intersected by segmental bolt sections 20 mounted tor longitudinal movement in the telly and the wedges 18 being provided with notches or seats 21 for engagement by said bolt sections, or more specifically by reinforced or thickened portions 22 thereot as shown in Figure 6.

The longitudinal movement of the bolt sections may be effected in a variety of ways, but preferably they are provided at their adjacent overlapping extremities with opposed racks 23 engaged by an interposed pinion 24 of which the stem 25 is mounted in a suitable bearing in the telly and has a head 2G which is accessible by a wrench or 'unilar tool from the inner surtace of the ell Obviously in removing the rim, after having actuated the bolt to release the wedges 18, the rim adjacent to the overlapping eX- tremities ot the bolt sections, or at a point remote from the valve tube may be moved transversely or laterally with relation to the wheel telly, after which the rim may be raised or moved radially with relation to the telly to withdraw the valve tube trom the opening 11 and at the same time disengage the interlocking elements 14 and 15.

Having thus described the invention, what l claim is A wheel having a felly member, a rim member, one of Said members having side flanges, lugs spanning the said flanges, lugs on the other member to engage opposite sides of the first mentioned lugs, ianges joining the first mentioned flanges of the wedges and bolts having cooperating enother member to provide seats and having largements for the purpose specied. Y il@ cutaway portions, bolts slidable across said n testimony whereof I affix my signature seats through said cutaway portions, said in presence of two witnesses.

bolts having rack teeth, operating gearing ALFRED MATHIS. engaging said rack teeth, the other member Witnesses: v having wedges adapted to enter said seats C. W. ALLEN, and notches to receive said bolts, and said GERTIE RICHARDSON.
